one of the simplest methods for short-term handling and storage of fish is the refrigeration in combination with dip treatments. this study was conducted to determine the effect of pre-storage α-tocopherol acetate dipping treatments on lipid stability of refrigerated rainbow trout fillets. trout fillets were dipped in α-tocopherol acetate solutions (200 and 500 mg kg-1 flesh) and subsequently s...

Twenty-four crossbred beef cows were used to investigate the concentration of alpha-tocopherol in plasma and tissues following oral administration of four tocopherol sources. Animals were allotted to the following treatments: DL-alpha-tocopherol, D-alpha-tocopherol, DL-tocopheryl acetate and D-alpha-tocopheryl acetate. Animals received a daily oral dose of 1,000 IU of the respective tocopherol ...

BACKGROUND In adults, RRR-alpha-tocopheryl acetate (natural vitamin E) has approximately twice the biological activity of all-rac-alpha-tocopherol (synthetic vitamin E). Similar studies have not been done in term infants. OBJECTIVE We evaluated the vitamin E and antioxidant status of term infants fed formulas differing in the amount and form of vitamin E acetate. DESIGN A controlled, blinde...

A rapid, sensitive method has been developed for the simultaneous determination of retinol acetate, delta-, gamma-, alpha-tocopherol and alpha-tocopherol acetate. We compare two experimental procedures for simultaneous direct solvent extraction of these vitamins without previous saponification. Method I: the fat milk sample was extracted with ethanol-hexane and injected directly into the chroma...

To study the mechanisms of discrimination between various forms of vitamin E, four normal subjects, one patient with lipoprotein lipase deficiency, and three patients with abnormal apolipoprotein B-100 production were given an oral dose containing three tocopherols labeled with differing amounts of deuterium (2R,4'R,8'R-alpha-(5,7-(C2H3)2)tocopheryl acetate (d6-RRR-alpha-tocopheryl acetate), 2S...

This study evaluated the effect of vitamin E supplementation source, and the dose given to sows or piglets, on the fatty acid profile of colostrum, milk, subcutaneous and intramuscular fat, and the oxidative status of piglets at 39 days of age. Sows (n = 10) were given 150 mg dl-α-tocopheryl acetate/d in feed, or 75 or 50 mg micellized-d-α-tocopherol/d in water from Day 103 of pregnancy. Weanin...

A rapid, selective and sensitive ultra-performance liquid chromatography method has been developed for the detection and quantification of tocopherols and retinol in human plasma. Alpha-tocopherol, gamma-tocopherol and retinol are assayed using fluorescence detection. Excitation/emission wavelengths are 295/330 nm and 325/470 nm for the analysis of both tocopherols and retinol, respectively. Re...
